the original feature, e.g. glTF material or per-point color in the tile.
<p>
When <code>REPLACE</code> or <code>MIX</code> are used and the source color is a glTF material, the technique must assign the
<code>_3DTILESDIFFUSE</code> semantic to the diffuse color parameter. Otherwise only <code>HIGHLIGHT</code> is supported.

A feature whose color evaluates to white (1.0, 1.0, 1.0) is always rendered without color blending, regardless of the

A Command is a function with an extra <code>canExecute</code> observable property to determine

a command has been or is about to be executed.

<div class="description">
    Initiates a terrain height query for an array of <a href="Cartographic.html"><code>Cartographic</code></a> positions by
requesting tiles from a terrain provider, sampling, and interpolating.  The interpolation
matches the triangles used to render the terrain at the specified level.  The query
happens asynchronously, so this function returns a promise that is resolved when
the query completes.  Each point height is modified in place.  If a height can not be
determined because no terrain data is available for the specified level at that location,
or another error occurs, the height is set to undefined.  As is typical of the
<a href="Cartographic.html"><code>Cartographic</code></a> type, the supplied height is a height above the reference ellipsoid
(such as <a href="Ellipsoid.html#.WGS84"><code>Ellipsoid.WGS84</code></a>) rather than an altitude above mean sea level.  In other
words, it will not necessarily be 0.0 if sampled in the ocean. This function needs the
terrain level of detail as input, if you need to get the altitude of the terrain as precisely
as possible (i.e. with maximum level of detail) use <a href="global.html#sampleTerrainMostDetailed"><code>sampleTerrainMostDetailed</code></a>.

    Options to control the setting up of a WebGL Context.

<code>allowTextureFilterAnisotropic</code> defaults to true, which enables
anisotropic texture filtering when the WebGL extension is supported.
Setting this to false will improve performance, but hurt visual quality,
especially for horizon views.

See <a href="https://registry.khronos.org/webgl/specs/latest/1.0/#5.2">WebGLContextAttributes</a>

<code>alpha</code> defaults to false, which can improve performance
compared to the standard WebGL default of true.  If an application needs
to composite Cesium above other HTML elements using alpha-blending, set
<code>alpha</code> to true.
